This invention relates to the class of boats and particularly smallboats of the type to be propelled by a paddle.

The primary object of the present invention .is to provide a metal boatin the nature of a passenger compartment may become completely filledwith water.

The invention will be best understood from a consideration of thefollowing detailed description taken in connection with the accompayingdrawings forming a part of the present invention with the understanding,however, that the invention is not confinedto any strict conformity withthe showing of the drawings but may be changed or modified as long assuch changes or modifications mark no materlal departure from thesallent features of the'invention as expressed in the appended claims.

In the drawings Figure 1 shows a boat constructed in accordance with thepresent invention, in top plan;

Figure 2 is a view in side elevation of a major portion of the boat;

the two portions of the hull of the boat. Each of these hull sections 1forms one-half of the complete hull, they being joined together as isclearly shown in Figure 1 to form the central transverse seam 2. Each ofthe hull sections 1 is made of a single elongated sheet of metal whichis folded along its longitudinal center to form a keel flange 3 andhasone end edge out to form the rounded edges 4 which are brought togetherand secured to form one end of the hull unit. These rounded edges 4; arewelded or otherwise suitably secured together to form a water-tight seamand the longitudinal edges of the sheet of which the hull section isformed are-then turned up to form the gunwales 5.

Each edge of each gunwale is folded inwardly and then reversely foldedor turned upwardly to form the groove or channel 6 along the inner facethereof, these channels being joined together at the end of the hullunit, as indicated at 7 in Figure 4.

At suitablepoints in each hull section 1 there are positioned thetransverse panels or bulkheads 8, the edges of which are secured to thesupporting hull section in such a manner as to form an air andwater-tight joint or connection therewith. r

The midships or inner ends of the hull sections 1 are arranged in theoverlapping relation shown in Figure 6 to form the joint 2' 9.. Each ofthese decksections is substan- V tially triangular in outline and istransversely arcuate as shown. Each longitudinal edge is provided witha-down-turned flange strip 10' and the transverse end edge of each hasan elongated recess 11 cut therein which forms a portion of thewell-hole by which a rider enters the hull of the boat.

As will be readily understood each triangular portion 9 of the deckstructure overlies a hull section 1 and the flanges 10 fit into thechannels 6 thereof and are soldered or otherwise suitably securedtherein.

The bulkheads 8 after being placed in position are welded or otherwisesuitably secured around their edges to the hull and to the deck so as toform the dead air chambers 12 and 13 at the bow and stern of the boat,the chamber 14 lying between the two inner or central bulkheads 13providing the passenger compartment. The abutting ends of the decksections 9 are suitably secured together and the recesses 11 thereinform the complete elongated opening by which the rider enters thecompartment 14.

Secured about the edge of the opening through the deck, is a verticallydisposed collar 15, the lower edge of which is formed to provide thenarrow flanges 16 which are alternately positioned against the upper andlower surfaces of the deck of the boat, to which they are riveted orotherwise suitably secured, the body of the collar 15 being fitted downinto the opening through the deck. as is clearly shown in Figures 3 and5. The top edge of the collar 15 is given a double turn to form therelatively thick edge portion 17 which forms a guard to prevent theinjury of the occupant against the top edge of the collar.

From the foregoing it will be readily seen that a boat constructed inaccordance with the present invention may be made perfectly water-tightand non-sinkable and can be easily propelled over the water by anoccupant positioned in the well 11 and wielding a single or doublebladed paddle.

Having thus described my invention, what I claim is 2- 1. A boat of thecharacter described comprising a sheet metal hull. a channel formedthroughout the edges of the gunwales of the hull, a sheet metal deckcovering said hull. inturned flanges formed throughout the edges of thedeck and having water-tight engagement in said channels. means toprovide an air and water-t ght chamber in each end of the boat. saiddeck having a central opening formed therethrough, and a guard collarsurrounding said opening and stand ing up from the deck.

2. A boat of the character described comprising a sheet metal hull ponted at both ends, a keel formed longitudinall of the hull andconstituting a fold of the metal thereof. a channel formed along theinner edge of each gunwale of the hu l and constitut ng an infold of thehull bodv. a sheet metal deck covering said hull. a flange formed alongeach longitudinal edge of the deck body and constituting an integralinturned portion of the same and secured in a gunwale channel to form awater-tight joint therewith, said deck having a well-hole therethrough,and a guard collar secured in said well-hole and projecting upwardlyabove said deck.

3. A boat of the character described comprising a hull formed in twosections, each of said hull sections constituting a single body of sheetmetal folded intermediate its ends to form a keel portion and having oneend formed to provide two rounded portions which are secured together toform a leakproof connection, the other ends of said hull sections beingoined together and forming a central transverse seam, a channel formedalong the inner edge of each gunwale of each section, a deck formed ofsheet metal material in two portions, each of said portions beingsubstantially triangular and having an inturned flange along theconvergent edges thereof, each of the flanges of each deck portionfitting into a channel of a hull portion and forming a watertightconnection therewith, the other edges of said deck portions beingsecured together, said deck portions having recesses formed therein attheir abutting ends to provide an entrance to the hull, and anupstanding collar secured in said entrance and projecting above the deckand having water-proof connection with the deck.

4. A boat of the character described comprising a hull formed in twosections, each of said hull sections constituting a single body of sheetmetal folded intermediate its ends to form a keel portion and having oneend formed to provide two rounded portions which are secured together toform a leakproof connection, the other ends of said hull sections beingjoined together and forming a central transverse seam, a channel formedalong the inner edge of each gunwale of each section, a deck formed ofsheet metal material in two portions, each of said portions beingsubstantially triangular and having an inturned flange along theconvergent edges thereof, each of the flanges of each deck portionfitting into a channel of a hull portion and forming a water-tightconnection therewith, the other edges of said deck portions beingsecured together, said deck portions having recesses formed therein attheir abutting ends to provide an entrance to the hull, an upstandingcollar secured in said entrance and projecting above the deck and havingwater-proof connection with the deck, and bulkhead partitions in thehull having Watertight connection about their edges with the hull andwith the deck and forming buoy chambers at the bow and stern of theboat.

5. A boat of the character described, comprising a sheet metal hull, achannel formed throughout the edges of the gunwales of the hull, a sheetmetal deck covering said hull, inturned flanges formed throughout theedges or" the deck and having water-tight engagement in said channels,and means to provide an air and water-tight chamber in each end of theboat, said deck having a central opening formed therethrough.

6. A boat comprising a hull of sheet metal, a keel extendinglongitudinally of the hull and constituting a fold in the metal, a deckover the hull, a flange along the edge of the hull formed to provide agroove, and a flange formed along the edge of the deck adapted to fitinto sald groove to form a water-tight connection therewith.

7. The herein described method of forming a sheet metal body hull of twosheets of metal, which consists in cutting one end of one sheetlongitudinally to form two rounded edges, then forming a longitudinalkeel fold in the cut sheet from the inner end of the cut to the oppositeend of the sheet, then bowing the cut sheet transversely to bring therounded out edges together and securing the same, then forming a centrallongitudinal keel fold in the other sheet and transversely bowing thesheet, then fitting and securing one end of the second mentioned sheetto the other end of the first sheet from the cut end, and finallyclosing the other end of the second mentioned sheet.

8. A boat of sheet metal comprising a hull formed of two sections, eachsection consisting of a single sheet of metal having a pointed end and arounded out Water or stem, the metal of each section, from the beginningof the rounded stem, being folded longitudinally to form a closed foldkeel extending throughout the length of the section and of the samedepth throughout, the other ends of the sections being engaged one withthe other and secured to form a water-tight seam to extend transverselyof the boat, the keels of the two sections being in abutting relation atthe said other ends.

9. A boat of sheet metal comprising a hull formed of two sections, eachsection consisting of a single sheet of metal having a pointed end and arounded out water or stem, the metal of each section, from the beginningof the rounded stem, being folded longitudinally to form a closed foldkeel extending throughout the length of the section and of the samedepth throughout, the other ends of the sections being engaged one withthe other and secured to form a water-tight seam to extend transverselyof the boat, the keels of the two sections being in abutting relation atthe said other ends, and a deck overlying a portion of the hull andsecured about its edges to the gunwales of the hull.
